VERTEX 100-ST1 is a fatty acid-treated magnesium hydroxide product that provides superior fire performance and enhanced mechanical properties when used to make fire-rated compounds. The surface treatment promotes uniform dispersion of the magnesium hydroxide in the polymer used and enhances compounding and processing throughput, providing enhanced compound performance especially for high-loading applications. VERTEX 100-ST1 decomposes at 330°C to form water and magnesium oxide, releasing heat to suppress flames and smoke. This makes VERTEX 100-ST1 ideal for applications requiring fire retardancy and durability.
